Monitoring DHCP scope on WLC 5508

Hi,

I have DHCP configured on the anchor controller but I don't know when DHCP scope is full on it. Do you have any idea or experience how to monitoring exhausted DHCP scope on WLC 5508?

This questions comes up from time to time. The WLC wasnt really built to handle DHCP by this I mean it doesn't do reservations, deletes leases after reboots etc .. So no ... sorry

 

But you have 2 options -- Make the scope bigger or move it to a real DHCP server ..

Ok but WLC can send syslog messages and base on this we can create an alarm. When DHCP scope is full on the WLC then controller inform us about this:

 

DHCP Server: Nov 13 11:34:56.321: %DHCP-3-SEND_OFFER_FAIL: dhcpd.c:278 Unable to send DHCP offer. Could not allocate appropriate ip address from the scope
*DHCP Server: Nov 13 11:34:56.321: %DHCP-4-ADDR_NOT_ALLOCATED: serverpacket.c:205 No IP addresses to give -- OFFER abandoned -- packet dropped
*DHCP Server: Nov 13 11:34:52.416: %DHCP-3-SEND_OFFER_FAIL: dhcpd.c:278 Unable to send DHCP offer. Could not allocate appropriate ip address from the scope
*DHCP Server: Nov 13 11:34:52.416: %DHCP-4-ADDR_NOT_ALLOCATED: serverpacket.c:205 No IP addresses to give -- OFFER abandoned -- packet dropped

 

so If only I could detect this sentence from the syslog messages than I could create an alarm.
